2) A simple machine requires 8.3 N of force to obtain an output force of 32 N. What is the
mechanical advantage of the machine?

The mechanical advantage of the machine is 3.9.

Explanation:

A simple machine is a machine which gives the output if we give the required input, and so the output always depends on the input force. Sometimes machines can also reduce the input force to get the required output and the ratio of output to input force is called as the mechanical advantage.

MA =

Here F₀ , output force = 32 N

, input force = 8.3 N

MA =

     = 3.9

So the mechanical advantage of the machine is 3.9.

c) should be the answer.
